        <p> Find the intersection of a line starting in the center of the SVG node ending in the point <code>ref</code> (an object of the form <code>{ x: Number, y: Number }</code>). <code>target</code> is an SVG element to which this node's transformations are relative to. In JointJS, <code>target</code> is usually the <code>paper.viewport</code> SVG group element. Note that <code>ref</code> point must be in the coordinate system of the <code>target</code> for this function to work properly. This function returns a point in the <code>target</code> coordinte system (the same system as <code>ref</code> is in) if an intersection is found. Returns <code>undefined</code> otherwise.</p>
